Every so often a handout or document published by a library comes across my desk that makes me squint or shake my head. The problem is frequently with bad design, colors, or layout. Many times the problem is when the author, trying to be cute or unique, decides to use a fancy font. Even at my library I'll make the argument that a simple sans serif font like Arial should be used. It is not uncommon for the reaction to be a look of "what do you know? You're not a graphic artist!"
Apparently the students’ brains mistook the ease of reading about exercise for the ease of actually doing push-ups and crunches, and this misunderstanding motivated them to think about a life change. Those who struggled through the Japanese brushstrokes had no intention of heading to the gym; the reading alone tired them out.
While the fonts used in the study were dramatically different, the research does indicate that font choice can impact the effectiveness of library handouts.
